Given all the hype about the 787 (and this is NOT about it's problems). The jury seems to be out on the A380..will it become "the" 747 of the future..the A350 seems to me as a bigger 787. If you envision 20 years from now what do you think the 797 is going to be? Do you think Boeing is already planning and sketching yet? Will it be another tube with wings and 2 engines? Another 4 hole airplane? A flying wing? Suborbital? Or a 737 or 757 replacement and we won't see a major aviation breakthrough until Boeing starts up the 808 series?
The world is missing love, let's use our flights to spread it!

The 737 replacemet will be the 797, its going to be the next new jet from Boeing. The 777( 777NG) will have the high end, the 787 will have the 767 & 777-200ER market and the 797 will have the 737 & 757 market.
My guess is that the 797 will be a 737 replacement. I hope Boeing don't waste the name on some weird plane concept that is never going to happen. I am sure that some engineer is spending his lunchtime sketching up the next futuristic plane. I doubt they are currently spending a lot of manpower on the project considering how busy they are with their existing projects and future derivatives.
It doesn't seem like a bigger 787, it IS a 777 replacement.
Quoting VC10er (Thread starter): If you envision 20 years from now what do you think the 797 is going to be?
I would venture a guess it will be Y1, unfortunately I think it will still be a tube with wings with engines underneath. I hope it will be a BWB, but I don't think airport infrastructure will be ready for that.
Agreed. Considering the cockpit design of the -07,-27, -37 being the same (with differing lower nose/fuselage contours), and the 767 nose section grafted onto the 777....I would not be surprised if you see the same cockpit section being reused on the 797.
Radical design changes? Can't see it happening. "If it ain't broke, don't fix it..." will be the continuing thought process, with tweaks on aerodynamic efficiencies. Blended Wing or some sort of Eliptical Wing...just a bit too much for what really is *sigh* just a Sky Bus.

I don't think there will be a radical design change, although I expect to see major developments in materials and engine technology being incorporated - GTF certainly, but what might come between now and 2020-22, when the 797 is likely to enter service.
1. As to market, the 100-130 seat market is likely to be quite full, with several different types competing for it; I see there being three fuselage sizes, taking the aircraft from about 160 (2 class)/190 (1 class) to about 240 (2 class)/270 (1 class); the aircraft, while primarily aimed at existing 737 routes, will have an ETOPS option and should be able to cover up to 4,000 miles, enough for short transatlantic hops (E Coast-Dublin, AMS, BRU,CDG).
2. Fuselage; abandon the current single aisle design, which - let's face it - Boeing has got pretty good value out of! I see the fuselage cross section being closer to the 767: 2-3-2 in a standard layout, with 2-4-2 being available in a high density layout.

The 350 may be a 772LR replacement but until it has a freighter variant it leaves the 777F untouched and as we all know the automatic death knell for the 773ER has yet to toll. And I would say it is those two 777 variants that will make up 90% of all 777 sales over the next 5 years...stay tuned.
